2C – 2 FRONT SUSPENSION
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
FRONT SUSPENSION
The front suspension for this vehicle is a combination
knuckle/strut and spring design.
The control arms pivot from the body. The lower control
arm pivots use rubber bushing. The upper end of the
strut is isolated by a rubber mount and contains a bear-
ing to allow the wheel to turn.
The lower end of the steering knuckle pivots on a ball
joint bolted to the control arm. The ball joint is fastened
to the steering knuckle with a bolt.When servicing the control arm-to-body attachment and
the stabilizer shaft-to-body insulators, make sure the at-
taching bolts are loose until the control arms are moved
to the trim height, which is curb height. Trim height is the
normal position to which the control arms move when
the vehicle is sitting on the ground. Refer to “General
Specifications” in this section.
